Revolutionary hardware unveils new quantum computing model

A potentially game-changing theoretical approach to quantum computing hardware avoids much of the problematic complexity found in current quantum computers. The strategy implements an algorithm in natural quantum interactions to process a variety of real-world problems faster than classical computers or conventional gate-based quantum computers can.

“Our finding eliminates many challenging requirements for quantum hardware,” said Nikolai Sinitsyn, a at Los Alamos National Laboratory. He is co-author of a paper on the approach in the journal Physical Review A. “Natural systems, such as the electronic spins of defects in diamond, have precisely the type of interactions needed for our process.”

Sinitsyn said the team hopes to collaborate with experimental physicists also at Los Alamos to demonstrate their approach using ultracold atoms. Modern technologies in are sufficiently advanced to demonstrate such computations with about 40 to 60 qubits, he said, which is enough to solve many problems not currently accessible by classical, or binary, computation. A is the basic unit of quantum information, analogous to a bit in familiar classical computing.

Gold buckyballs, oft-used nanoparticle ‘seeds’ are one and the same

Rice University chemists have discovered that tiny gold “seed” particles, a key ingredient in one of the most common nanoparticle recipes, are one and the same as gold buckyballs, 32-atom spherical molecules that are cousins of the carbon buckyballs discovered at Rice in 1985.

Carbon buckyballs are hollow 60-atom molecules that were co-discovered and named by the late Rice chemist Richard Smalley. He dubbed them “buckminsterfullerenes” because their atomic structure reminded him of architect Buckminster Fuller’s geodesic domes, and the “fullerene” family has grown to include dozens of hollow molecules.

In 2019, Rice chemists Matthew Jones and Liang Qiao discovered that golden fullerenes are the gold “seed” particles chemists have long used to make gold nanoparticles. The find came just a few months after the first reported synthesis of gold buckyballs, and it revealed chemists had unknowingly been using the golden molecules for decades.

Strange Landscape of Particles Inside a Proton Mapped Like Never Before

The protons and neutrons making up atomic nuclei are made up of a trio of even smaller fundamental particles known as quarks.

A new study has now mapped out in unprecedented detail the distribution of the different kinds of quark inside a proton, expanding on our understanding of this all-important part of an atom.

Although the quantum landscape within protons is a seething mess of quarks and their opposing antiquarks popping in and out of existence, there is a general dominance of two ‘flavors’ over the others; two up-flavor quarks and a single down-flavor quark.

Can we understand the universe? | Sheldrake & Hossenfelder go head to head on dark matter IN FULL

Sabine Hossenfelder, Rupert Sheldrake and Bjorn Ekeberg go head to head on consciousness, panpsychism, physics and dard matter.

“Not only is the universe stranger than we think. It is stranger than we can think.” So argued Niels Bohr, one of the founders of quantum theory. We imagine our theories uncover how things are but, from quantum particles to dark matter, at fundamental levels the closer we get to what we imagine to be reality the stranger and more incomprehensible it appears to become.

Might science, and philosophy one day stretch to meet the universe’s strangeness? Or is the universe not so strange after all? Or should we give up the idea that we can uncover the essential character of the world, and with Bohr conclude that the strangeness of the universe and the quantum world transcend the limits of the human mind?

Stephen Wolfram starts by discussing the second law of thermodynamics — the idea that entropy, or disorder, tends to increase over time. He talks about how this law seems intuitively true, but has been difficult to prove. Wolfram outlines his decades-long quest to fully understand the second law, including failed early attempts to simulate particles mixing as a 12-year-old. He explains how irreversibility arises from the computational irreducibility of underlying physical processes coupled with our limited ability as observers to do the computations needed to “decrypt” the microscopic details.

The conversation then shifts to discussing language and how concepts allow us to communicate shared ideas between minds positioned in different parts of “rule space.” Wolfram talks about the successes and limitations of using large language models to generate Wolfram Language code from natural language prompts. He sees it as a useful tool for getting started programming, but one still needs human refinement.

“Quantum Avalanche” — A Phenomenon That May Revolutionize Microelectronics and Supercomputing

New Study Solves Mystery on Insulator-to-Metal Transition

A study explored insulator-to-metal transitions, uncovering discrepancies in the traditional Landau-Zener formula and offering new insights into resistive switching. By using computer simulations, the research highlights the quantum mechanics involved and suggests that electronic and thermal switching can arise simultaneously, with potential applications in microelectronics and neuromorphic computing.

Looking only at their subatomic particles, most materials can be placed into one of two categories.

Tiny particle’s ‘wobble’ could be start of a major discovery — scientists

The “wobble” of a tiny particle known as a muon is once again challenging our understanding of physics and could be the start of a major discovery, scientists have said.

For the third time, findings from experiments have shown this particle does not behave as predicted by the Standard Model – the rulebook physicists use to describe and understand how the universe works at the subatomic level.

Scientists said their latest results, which have been submitted to the journal Physical Review Letters, reinforce measurements of the muon’s wobble in previous experiments and are even more precise.
